FILE - Former Georgia Lt. Gov. Geoff Duncan leaves the Fulton County Courthouse, Aug. 14, 2023, in Atlanta. Nikki Haley exceeded expectations by becoming the last Republican standing against Donald Trump in the Republican presidential nomination fight. She still hasn't fallen in line and endorsed her former rival. Duncan, a Republican who had endorsed Haley, formally endorsed President Joe Biden earlier in the month. Duncan hopes Haley doesn't ultimately endorse Trump as so many of Trump's high-profile Republican critics have done. (AP Photo/Alex Slitz, File)
